Renewable energyRenewable energy is a source of energy that can never be exhausted.
We can obtain renewable energy from the sun (solar energy), from the water (hydropower), from the wind (windmills), from hot dry rocks, magma, hot water springs (geothermal) and even from firewood, animal manure, crop residues and waste (Biomass).

As of April 2, Round Rock, Texas-based Dell is powering 100 percent of its 2.1 million square-foot global headquarters campus with 100 percent green power.

"It's time for our industry to take a lead role in creating a clean energy future," said Paul Bell, president, Dell Americas. "We are challenging every technology company to work with their suppliers and partners in integrating green power and energy-efficient strategies into their operations."

Dell is using all of the power generated from Waste Management's Austin Community Landfill gas-to-energy plant, meeting 40 percent of Dell headquarters’ campus power needs. The remaining 60 percent comes from existing wind farms and is provided by TXU Energy.

The computer company also announced it is increasing green power use for its Austin Parmer Campus, provided by Austin Energy, from 8 percent to 17 percent. Dell also is powering its Twin Falls, Idaho, facility with 100 percent green power, 97 percent of which is wind power and 3 percent solar.

In September 2007, Dell announced it would make company owned and leased facilities "carbon neutral" in 2008 through a strategy of improving energy-efficiency in its operations and maximizing the purchase of renewable power. This commitment is part of the company's climate strategy which also seeks to minimize carbon impact of supplier operations and customer product use.
